This research presents an improvement of the physical and mechanical properties of composite board (com-ply) made of Oriented Strand Board (OSB) coated with wood veneer of Pine (Pinus merkusii), Avocado (Persea Americana) and Mahogany (Swietenia mahogany). 1.5 mm thick veneers of those three wood types were adhered to the surface of OSB using two adhesive types: epoxy and isocyanate. The adhesive with the glue spread of $250g\;m^{-2}$ applied using single glue line was spread and then cold pressed with the pressure of $15kg\;cm^{-2}$ for 3 hours. The research result showed an improving dimension stability of com-ply, but not found on all parameters of physical property test. The moisture content seemed to be influenced by the com-ply type, yet not related to its thickness swelling, water absorption and linear expansion. The exception took place in the parallel linear expansion when immersed for 2 hours. The highest to the lowest increases of MOE and MOR were consecutively found on OSB coated with wood veneer of Pine, Mahogany and Avocado. However, the increases were statistically insignificant. The highest increasing screw hold power was found at the com-ply type AE (avocado veneer and epoxy adhesive) that was by 28%.

In general, final width of hot strip should be accomplished in this stage because width reduction of strip hardly appears during typical finishing mill. However, it is difficult to control the width of strip in the roughing mill process as the horizontal rolling of strip is subsequently performed after the vertical rolling. It is therefore important to obtain the deformation rolling direction on strip width to minimize the width spread of strip during horizontal rolling after vertical rolling. Generally there is Sizing press type and Edger-roll type. The width reduction process in sizing press has small amount of width spread compared with the edger. However, productivity by the sizing press process is much lower than those of the edger. In this study, sizing press and Edger-roll process parameters in a sheet rolling mill were set at specified values and the effect of the change in these parameters on product quality and process performance were evaluated.

Purpose: More and more marketers use social media platforms to create and spread information called Marketer Generated Content (MGC) to inform consumers of products. MGC often embeds product purchase links, thus directing consumers to online distribution channels for online purchases. This study examined the effect of social media MGC on consumers' willingness to buy online in the anchor of consumers' perspective to answer the question of "how social media generated content support corporate online distribution". Research design, data, and methodology: According to the means-end-chain theory, we introduce perceived value and continuous following intention as chain mediators to explain the mechanism of MGC influence on consumers' online purchase intention and consider product type to discuss boundary conditions. Two experiments were designed to test hypothesizes. Results and Conclusion: First, emotional MGC (vs. informational MGC) has lower (higher) perceived utility (hedonic) value. Second, perceived value has a significant mediate role in the effect of MGC on continuous following intention. Third, perceived value and continuous following intention significantly and sequentially mediated the effect of MGC on online purchase intention. Through the sequential mediations of perceived utility value and continuous following intention, Informational MGC of search products significantly increase online purchase intentions. Another parallel sequential mediation, including perceived hedonic, emotional MGC of experience products, partially enhanced online purchase intentions. Finally, this study gives implications for how corporates can use social media MGC to promote product sales online.

The convenience and flexibility due to the spread of Internet allowed consumers to easily participate in marketing activity. Consumers want to participate in designing, manufacturing, delivering of products and service by expressing their opinions to the companies because they want to buy customized goods where their requirements are incorporated. We can expect that, through this interactive process of customization between consumers and companies, strong relationship quality may be built as a result of the interaction. The main purpose of this study is to examine the influence of consumer perception of customization on relationship quality in the e-business context. To accomplish this purpose, I reviewed the concept of customization, identified the perceptive factors of customization in e-business context (i.e., perception of participation level, assessment of flexibility), and examined the type of customization. Whether customization type generates varying degrees of perception of customization and relationship quality is revealed. As a result, collaborative product/service customization generated the highest relationship quality. Assembled product customization that was built based only on predicted consumer needs without any interaction between consumer and company showed a low level of relationship quality. And this type had no significant difference from standardized products. In short, there is a strong need for e-business companies to interact with consumers to improve relationship quality.

The emergence of the Internet has provided a new outlet for consumers who experience service failure from products and services, augmenting the traditional options of entry, voice and action. Consumers' negative word of mouth through online (word-of-mouse or eWOM) far exceeds traditional word of mouth (WOM) in respect of its potential effectiveness, speed and spread. This paper tries to figure out the service failure themes in the health care industry by analyzing online word-of-mouse using the critical incidents technique (CIT). Complaint themes in the area of healthcare are identified and analyzed. The results identify that major complaint theme differed according to the site type. Also, the findings indicate that delivery and customer services are critical issues when consumer makes negative WOM.

Bamboo culm comprises internodes and nodes and is tapered from the bottom to the top. Anatomically, bamboo culm comprises vascular bundles and parenchymal base tissue. The gross anatomical structure of a transverse section of any culm internode is determined by the shape, size, arrangement, and number of vascular bundles. The purpose of this research was to examine the morphology of culm and the distribution and shape of vascular bundles in Ampel bamboo (Bambusa vulgaris). Bamboo culms were harvested from the base. Test samples were obtained from a central 2-cm long segment of each internode across the entire length of the culm. Results showed an uneven spread of vascular bundles in the internode cross-section. Transitioning from the outer to the inner layer of the internode, the number of vascular bundles per unit area decreased and their shape was variable. The size of vascular bundles in the middle layer of the internode was greater than that of those in the outer and inner layers. The shape of vascular bundles was circular in the outer layer, which gradually transformed into vertical oval toward the middle layer and horizontal oval toward the inner layer. Vascular bundles were of type III and IV in the bottom of the culm and type III in the middle to the top of the culm.

스프링클러 설비는 화재 발생 시 화재를 초기에 제어 및 진압하는 설비로서 어떠한 화재 분위기에서도 스프링클러 헤드의 작동온도에서 정상적인 동작을 하여야 한다. 그러나 최근 화재성장속도가 느린 화재 발생 장소에서 일부 조기반응형 스프링클러 헤드가 정상적인 동작을 하지 않을 수 있다는 문제가 제기되고 있다. 이에 본 논문에서는 공동주택 침실규모의 모형실험 및 캐비넷형 버너를 이용하여 화재성장속도가 느린 조건을 형성하고 실제 현장에서 배관 내에 가해지는 최소압력인 0.2MPa 이상의 가압수를 공급하여 실험을 진행하였다. 실험결과 국내에서 사용되고 있는 과반수 이상의 플러쉬형 조기반응형 스프링클러 헤드에서 Cold Soldering 현상이 발생되면서 불완전하게 개방되는 것이 확인되었다. 이러한 현상은 화재 조기진압 및 제어에 실패하여 화재확산 및 인명피해의 원인이 될 수 있으므로 추가적인 연구를 통해 국내 형식승인 및 제품검사기준의 보완의 필요할 것으로 판단된다.
